MOTOR-TRUCK.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed March 25, 1907. Serial No. 364,481,

To all whom it may concern:

Be it known that I, WILLIAM F. KIESEL, J12, a citizen of the UnitedStates, residing at Altoona, in the county of Blair and State ofPennsylvania, have invented certain new and useful Improvements inh/Iotor-Trucks, of which the following is a specification.

This invention relates to improvements in the method of hanging themotor frames upon the trucks of electric railway cars.

Heretofore it has been the practice to support the noses of the motorframes upon transoms which pass across the truck at each side of thebolster. This method of hanging introduces a couple into the forcesbrought into play upon the truck when the motors are in motion, whichcauses the wheels to be loaded irregularly, and also produces a tippingaction upon the truck frame, according to the direction in which the caris running. I

My object is to overcome this objectionable feature by so constructingthe truck and arranging the noses that the points of support thereforshall be directly under the center line of the center-plate.

I attain my object by arranging the parts in the manner illustrated inthe accompanying drawings, in which I have shown the motor framesapplied to a truck such as described in my Letters Patent No. 800,921,dated October 3, 1905; and in which Figure 1 represents a plan view ofthe truck, with two Westinghouse motors applied thereto; Fig. 2, alongitudinal sectional view showing the truck bolster cut at the centerand the axles cut at the ends of the motor frames; Fig. 3, a transversevertical section of the truck on the line aa in Fig. 1; and Figs. 4, 5,and 6, detail sectional views of the truck bolster and nose support on alarger scale.

Like numerals designate like parts in the several views.

As described in my said Letters Patent, the bolster 1 is formed of asteel plate bent into U-shaped cross section, so hung on the wheelpieces as to have freedom for vertical and lateral motion with respectto the wheel pieces, and consequently, to the wheels. The motor frames 2are mounted upon the axles in the usual manner, one at each side of thebolster; but, instead of providing the frames with noses resting upontransoms carried by the wheel pieces, I provide the frames with noses 3,positioned lower down upon the frames, and extending through openingsprovided therefor in the sides of the bolster to points directly beneaththe center-plate 4. Directly below the transverse center line of thecenter-plate is hung a suspension bar 5, upon the upper side of whichthe ends of the noses 3 rest, said noses being so formed as to pass byone another on opposite sides of the vertical center of the truck. Thesuspension bar is hung from the center-plate by means of the links 6,which are coupled by pins 7 to supporting' ears formed on thecenter-plate; said links passing downward through slots providedtherefor in the center-plate and bolster shell. This link suspensionpermits side play in the bolster without transferring said side play tothe motor noses; as will be evident from an inspection of the drawings.This side motion of the bolster extends to about one and threefourthsinches on either side of the central position, and must be allowed for,since the noses must remain in central posi tion; regardless of theswaying of the bolster.

To reinforce the bolster below the center-plate, I prowde a ribbedcasting 8, and at the center of the said casting I provide a downwardlyextending sleeve 9, through which the king-bolt 10 passes. Below thissleeve is a plate 11, which rests upon the upper side of the noses 3,said plate being held in position by the reduced extension from theking-bolt, and spring 12 is introduced between a shoulder on sleeve 9and said plate to press said plate upon the noses, holding them downupon the suspension bar with sufficient pressure to prevent chattering.

As there will be some side and end play of the noses upon the suspensionbar, due to the side play of the axles in the boxes, I fasten to the topof said bar a wear plate 13, the ends of which are turned up to limitthe side motion of the noses upon the suspension bar.

As it may be desirable to introduce a cushioning effeet between thebolster and the suspension bar, I may form the ears which receive thepin 7 separate from the center-plate, as upon the disks 14, as shown inFig. 5; and introduce springs 15 between said disks and thecenter-plate.

While I have shown my improved nose suspension as applied to my saidpatented truck, it will be understood that I do not limit it to suchapplication; since, by varying the arrangement and the manner ofapplying the parts, the device may be applied to other forms of trucks,without departing from the spirit of my invention.

1. The combination, with a car-truck having an independent bolster, of amotor-frame mounted upon one of the axles, a nose projecting from theframe opposite the axle, and a laterally movable support for the nosepositioned beneath the center line of the bolster.

2. The combination, with a car-truck having motorirames mounted upon theaxles and provided with oppositely disposed noses, of a laterallymovable suspension bar upon which the frame noses rest, said bar being"positioned beneath and parallel with the transverse center line of thecenter plate of the truck.

3. The combination, with a car-truck having an independent bolster uponwhich the center plate is mounted, of motor-frames mounted upon theaxles and provided with oppositely disposed noses, a suspension bar uponwhich the frame noses rest positioned beneath the center plate, and

What I claim and desire to secure by Letters Patent links pivotallymounted on the bolster at each side of the center plate and coupled tosaid bar.

4. The combination, with a car-truck having pendent bolster upon whichthe center-plate is mounted, of motor-frames mounted upon the truckaxles and mo vided with oppositely disposed noses adapted to lap pastone another beneath the center-plate on opposite sides of the verticalcenter of the bolster, a suspension bar upon which the ends of the nosesrest, and links coupling said bar to the bolster at opposite sides ofthe center-plate.

5. The combination, with a car-truck having an inde pendent bolster uponwhich the center-plate is mounted, of motor-frames mounted upon thetruck axles and pro vided with oppositely disposed noses adapted to lappast one another beneath the center-plate on opposite sides of thevertical center of the bolster, a suspension bar upon which the ends ofthe noses rest, links coupling said bar to the bolster at opposite sidesof the center-plate, a plate resting upon the top of the noses over thesuspension bar, a center-casting' in the bolster beneath thecenter-plate provided with a sleeve, a king-bolt passing through saidsleeve, a coiled spring mounted on the sleeve and pressing an indeuponthe plate above the noses, and a projection from the king-bolt to engageand hold said plate in place.

6. The combination, with a car truck having motorfraines mounted uponthe axles, of a suspension bar for the frame noses positioned beneaththe center-plate of the truck, links pivotally mounted on the truckbolster at each side of the center-plate and coupled to said bar attheir lower ends, and a spring pressed plate resting upon the top of thenoses above the suspension bar.

7. The combination, with a car-truck, having motorframes mounted uponthe axles, of a suspension bar for the frame noses positioned beneaththe conter-plate of the truck, and links pivotally mounted on springsupported bearings on the truck bolster at each side of the center-plateand coupled to said bar at their lower ends.

In testimony whereof I have affixed my signature, in presence of twowitnesses.
